Updated on November 18, 2016
The Earth is our home planet and the only one that we know for certain holds life.  A (mainly) blue sphere covered with swirls of white clouds, it is also the planet in our Solar System that we know most about.

As well as being our home, the Earth is also one of the most fascinating planets in our Solar system.

For one thing, it is the only planet where we know for sure that life exists! (Although there is still some hope that microorganisms might be found on Mars, or failing that, evidence that life existed there at some time in the past).

Other features that make the Earth unique are that it is the densest planet in the Solar System, and also that it is the largest of the four terrestrial planets.

It is also the only planet in the Solar System with a friendly atmosphere and gravity, where humans can live and breathe without the aid of space suits and space ships.

I hope that you enjoy reading my 15 fun facts about Planet Earth and find them interesting!

5. 70 percent of the globe's surface is covered by water. There are 5 oceans: the Atlantic, Pacific, Indian, Southern, and Arctic. The oceans are 2 miles deep on average.

Most of the Earth's surface is covered by water. There are five oceans: The Arctic, Pacific, Atlantic, Indian, and Southern. Life on the planet is believed to have originally developed in the sea, before moving to land.

6. The Earth's atmosphere consists of many layers, including the mesosphere, ionosphere, exosphere, and the thermosphere. The closest layer to the surface is called the troposphere. It is this layer that supports all life on Earth. At only 10 miles thick, the troposphere is also the thinnest layer of atmosphere.

7. The atmosphere is mainly made up of nitrogen (78%), oxygen (21%), argon (.93%), and carbon dioxide (0.03%).

8. The planet moves through space at 66,700 miles per hour.

The Moon viewed from Earth.  There are a number of theories regarding how The Moon was formed 4.5 billion years ago. The most widely accepted explanation currently is that it came from the debris of a collision between Earth and a Mars-sized body.

11. The globe's crust is made up of tectonic plates which move around and can clash with each other. As a result, there are about a million earthquakes taking place each year, although the vast majority of them are too weak to register.

The San Francisco earthquake of 1906 resulted in many fires breaking out, as well as buildings being damaged or flattened. Earthquakes are generally caused by the Earth's tectonic plates shifting.
